MAINTENANCE SECTION

5. Install the Backcap Front Spring (25) and the Control

Valve Assembly, seal end leading, over the shaft of
the Control Bushing. Install the Control Bushing
Seal in annular groove around the bushing shaft.

6. Fit the Backcap Rear Spring (24) against the Control

Valve and thread the entire assembly, spring end lead-
ing, into the Backcap (23). Using a spanner wrench,
tighten the Control Bushing in the Backcap.

7. Using an arbor press and a piece of tubing that con-

tacts the outer ring of the bearings, press the Front
Rotor Bearing (46) into the Front End Plate (45) and
the Rear Rotor Bearing (39) into the Rear
End Plate (38). (Refer to Dwg. TPD1274.)

8. Stand the Rotor (43) on the table of an arbor press.

It should be upright on a flat metal plate having a
clearance hole for the shaft. The shaft with the hex
must be upward.

9. Place a 0.001” (0.025 mm) shim on the upward

surface of the large portion of the rotor body. Using a
piece of tubing that contacts the inner ring of the
bearing, press the Front Rotor Bearing and Front End
Plate, End Plate leading, onto the shaft of the Rotor
until the End Plate contacts the shim. Remove the
shim. (Refer to Dwg. TPD1275.)

10. Coat each Vane (44) with a thin film of oil and insert

a Vane into each of the rotor vane slots with the
straight edge of the Vane outward.

11. For Model 1100PS4, install the Cylinder (41) over

the Vanes and Rotor making certain the End Plate
Alignment Dowel (46) enters the notch in the end
face of the Cylinder.
For Model 1900PS4, install the Cylinder Assembly
(41) over the Vanes and Rotor making certain the
Cylinder Alignment Pin (42) enters the hole in the
face of the Front End Plate.

12. Stand the assembly on an arbor press table so that the

rotor shaft on the front end plate end contacts the
table. Press the Rear End Plate Assembly, bearing
end trailing, onto the rotor shaft against the Cylinder.
For Model 1100PS4, make certain the End Plate
Alignment Dowel (40) enters the notch in the end
face of the Cylinder.
For Model 1900PS4, make certain the Cylinder
Alignment Pin (42) enters the notch in the end face of
the Cylinder.

13. Stand the assembly on a table with the Front End

Plate Assembly upward.

In the following step, take all precautions
necessary to prevent being burned by handling
warm or hot parts.

14. Using an induction coil or oven, heat the Motor

Housing (1) until the motor opening is large enough
to be placed over the Cylinder. At that time, install
the Housing over the Cylinder and Front End Plate
making sure the radial End Plate Alignment Pin in the
Rear End Plate enters the notch in the Motor
Housing.

15. Allow the assembly to cool and install the Backcap

Gasket (35) and the assembled Backcap (23).

16. Secure the Backcap to the Housing by installing the

three Backcap Mounting Screws (36) and Lock
Washers (37). Tighten each Screw between 45 and
50 in–lb (5.1 and 5.6 Nm) torque.

17. Install the Exhaust Deflector (22) in the bottom of the

handle of the Motor Housing and tighten it between
20 and 25 ft–lb (27 and 34 Nm) torque.

18. Thread the Inlet Bushing (2) into the bottom of the

handle of the Motor Housing (1) and tighten it be-
tween 30 and 35 ft–lb (40 and 47 Nm) torque.

19. Install the Throttle Rod Seal (9) in the groove on the

large hub of the Throttle Rod (8).

20. Install the Throttle Valve Seal (7) in the groove on the

large hub of the Throttle Valve (6).
